My JCW CM has a rattle coming from the engine area. It is not all the time, only at around 900 RPM's and around 1900 RPM's. It is always at the same RPM's every time. I opened the hood and had my wife keep it at 900 RPM's and it is definitely from under the removable n18 JCW plate that covers the spark plugs. When remove that cover it is still there .

Any ideas? I have no problems what so ever with performance.

Thanks!

 

Did you ever get this figured out? Does it sound like this?

 

I did get it fixed and the good news is that it was no big deal. Mine ended up being the heat shield on the turbo. I took it in and the had it fixed in 10min. Keep me posted.
